Aerodynamic Losses in Turbines with and without Film Cooling, as Influenced by Mainstream Turbulence, Surface Roughness, Airfoil Shape, and Mach Number

<table>Comparison of normalized integrated aerodynamic losses relative (minus-integrated aerodynamic losses with no film cooling) at different blowing ratios (after correction for the presence of trailing edge oblique shock waves) with correlating equation (<a href="https://static.hindawi.com/articles/ijrm/volume-2012/957421/figures/#EEq18">17</a>) for the symmetric airfoil with film cooling [<a href="/journals/ijrm/2012/957421/#B50">54</a>].</table>
